Wholesale Cylindrical roller

Category:

Rollers for crossed-roller bearings

Keywords:

The grease will become soft when rotating at high speed, causing leakage. When there is vibration, the grease will be squeezed and thrown from the raceway, and the soap structure of the grease will mechanically disintegrate and cause the grease to be destroyed or even thrown out. Cylindrical Roller Bearings.

The rolling element is a radial rolling bearing of cylindrical rollers. The internal structure of the cylindrical roller bearing adopts the parallel arrangement of the rollers, and the spacers or spacers are installed between the rollers, which can prevent the inclination of the rollers or the friction between the rollers, and effectively prevent the increase of the rotation torque. The matters needing attention when lubricating cylindrical roller bearings are summarized as follows.
1. Never mix incompatible oils and fats. If two incompatible oils are mixed, the consistency will usually become soft, and eventually the oil will be easily lost and cause damage.
2. The oil seal is a gateway that contains grease and cylindrical roller bearings from outside pollution. Many cylindrical roller bearings in the industry only use ball cages, some use metal oil seal systems, and some have automatic refueling systems, which are completely Open state, and bicycles usually cannot use such cylindrical roller bearings, otherwise the end of life will be declared only after the first cycle of grease exhaustion or contamination, and metal oil-sealed cylindrical roller bearings can also be used for a longer period of time. Avoid pollution, and can play a role in oil.
3. The grease will become soft when rotating at high speed, causing leakage. When there is vibration, the grease will be squeezed and thrown from the raceway, and the soap structure of the grease will mechanically disintegrate and cause the grease to be destroyed or even thrown out.
